Good day all.
If I might suggest reading some of this thread Location Block vs. Drop packets from and to hostile networks (listed at Spamhaus DROP, etc.) where there is discussion similar to this. What I have done, to reduce the length of the FW logs, is disable the “Drop packets from and to hostile networks…” and let the location block rule set drop the incoming traffic. I then set up a outgoing firewall rule to drop and log any outgoing traffic to a destination XD, that is the hostile networks. This should reduce your log burden and block the bad traffic.
Hope this helps.
